Scored across 5 tools
Each tool has a clear, non-overlapping responsibility: authentication lifecycle (login, logout, auth_status), problem lookup (get_problem), and submission history retrieval (get_submissions_by_date). There is no realistic ambiguity between tool purposes.
Most tools follow a readable snake_case pattern with clear verbs and nouns, such as get_problem and get_submissions_by_date. login/logout and auth_status are minor deviations but remain conventional and predictable.
Five tools is well-scoped for a focused LeetCode CN server handling authentication, problem data, and submission history. Each tool earns its place with no redundancy or bloat.
Authentication status/login/logout form a complete lifecycle, and problem fetching plus daily submission retrieval cover the core read-only workflows. Minor gaps such as broader problem search or submission detail endpoints are workable but not critical.
